What is the difference between renewable and non renewable energy? In this video I’m
going to be explaining the difference between renewable and non renewable energy. If you’re
studying this in class at the moment for GCSEs or equivalent then I think it’s going to
be really useful. Hey I’m Hayley Loren and I make videos to help you learn about science
and also discover engineering so if that sounds good to you then make sure you subscribe and
make sure you click the bell. So before we begin I just want to know from you whether
there’s anything to do with the topic of energy that you are struggling with right
now. Let me know in the comments below. So what is renewable and non renewable energy?
It’s a little confusing so I’m going to explain this with a glass of water and a very
big straw. Lets go to the kitchen. If I get myself a glass of water and drink it then
the water goes down and it doesn’t get replenished. So I have my enormous straw which I’m going
to put in the glass of water. Lets see if this works. And if I turn on the tap. So as
I actually drink the water in the glass the water is replenished, so it doesn’t run
out, it’s not depleted. It’s like renewable energy. So renewable energy doesn’t get
depleted when it’s used and non renewable energy does get depleted when it’s used.
Simple right? How about we run through some examples and head back upstairs. For non renewable
energy an example is fossil fuels and this is coal, oil and natural gas and as you know
and as I described in my previous video really quickly this is from millions of years ago
from organisms that died and they were buried over millions of years and due to loads of
pressure they basically turned into fossil fuels. There are only set quantities of fossil
fuels that are located in various pockets all over the earth which means that if you
use up the fossil fuels in one particular pocket then it doesn’t exist anymore, it’s
been depleted and it’s just gone. In my previous video I ran through quite a long
list, so there’s wave energy, tidal energy, biofuels, the sun and all of these things
don’t get used up when they are used they are not depleted. So just because you put
a solar panel on your roof it doesn’t mean the sun is going to stop shining and the wind
isn’t going to stop blowing just because you decide to put a wind turbine on a hill.
So just to summarise non renewable energy gets depleted when it’s used and an example
is fossil fuels. And renewable energy doesn’t get depleted when it’s used and there’s
lots of examples of this like wind, wave, tidal and the sun. Thankyou for watching the
video, I hope you found it useful. If you did then give it a thumbs up and if you’re
not already subscribed then do because I’ve got a lot more content coming your way. And
if you’re keen to carry on the topic of energy then I’ve got a card, so there’s
a little card at the top that you can click. So that’s it from me today and I will see
you next time.
